Application June 11, 1947, Serial No. 754,004

3 Claims. (Cl. e4 u) 1 The present application relates to a flexible cludes a splined end ll formed shaft by a releasable ball and spring arrangement.

Another object of the invention is to provide a simplified drive and driven shafts.

Another object of I and compact coupling.

The above and other objects and features of illustrated by way of example.

In the drawing:

taken along the lines H The invention is shown in the drawing of Fig. 1 as incorporated in a cylindrical housing I having end bearing plates 2 and 3 respectively. Mounted in the end bearing plate 2 is the bearis rotatably mounted a windings B of conven-- the invention is to provide Q vibration damping means. 1 The latter means inwhich slip over head portions l5 of thepins ll.

Engaged in the rubber bufl'er segments I4 is a cross pin l6 which extends through the driven cross pin it is releasably fixed in the shaft 5 by a ball 11, and spring l8 mounted pin It, as best shown in Fig. 1, pin it in place so as to prevent in field service.

From the foregoing, if will be seen that the segments it may be easily replaced by slipping the same over the heads I! of the pins l3.

M in operating relation. I

Moreover, the arrangement of the buffer segments H as shown, permits a satisfactory drive in spite of misalignment of the'driving and driven driving shaft, a plate amxed to said driving shaft, pin members axially extending from said plate, a pair of rubber buffer segments carried by said pin members; a cross pin releasably mounted in said driven shaft for engagement in said buffer lbly engage biased by said spring into member in engaging relation with said butler segments.

3. A flexible coupling, comprising. in combination, a driving shaft, a driven shaft. a plate aftlxed to said driving shalt, pin members projectin: from said plate, a pair of rubber buffer segments carried by said pin. members, said pin members having head portions ior releasably securing said butler segments to said plate, a cross pin projecting from said driven shaft to engage at opposite ends in said buffer segments, said driven shalt having a channel extending longitudinally therein, a spring positioned in said channel, a ball positioned in said channel and biased by said spring, said cross pin having a re- 15 ee'ss formed therein to: ensasement by said ball so as to releasabiy lock said bufler segments in clolupiing relation between said driving and driven s afts.
